In this video, I demonstrate two simple electrical methods for metal etching that serve as alternatives to traditional engraving, suitable for various metal restoration and modification projects.

While there are plenty of self-contained mobile-friendly laser engravers on the market today, most don't come equipped with a trap door.

How metals can be used depends particularly on the characteristics of their surfaces. A research team has discovered how they can change the surface properties without affecting the mechanical ...

Abstract: This study presents an express technology for the electrochemical etching of Gallium Arsenide (GaAs) to form massive island pores. The n-type GaAs (Ill) single crystal plates are processed ...
